ANSYS Rocky 2024 R1 v24.1.0 (x64)

New Coupling Features
-Rocky now has a 2-Way Thermal Coupling with Ansys Mechanical through System Coupling.
Performance Improvements
-Simulation performance for models that require extensive particle sorting was improved for GPU simulations.
-Simulation performance for geometries with large triangle count was improved for GPU simulations.
New Particles Feature
-The ability to add flexible fibers and flexible shells as particle assembly parts was added as a Beta feature.
New SPH Features
-The ability to set wall boundary condition per wall was added.
-The interaction between Coarse-Grained DEM particles and SPH elements was implemented.
-The ability to calculate the Heat Transfer Coefficient (HTC) on walls was added.
New API:Solver Features
-The ability to build custom viscosity modules was added.
-The ability to freeze SPH elements was added.
-The ability to build custom surface tension modules was added.
-The ability to access the nearest point of a Point Cloud was added for SPH hooks.
-The ability to identity if an SPH element is inside or outside a Region of Interest was added.
Post-processing Improvements
-The ability of selecting properties that will be saved in disk was implemented. For post-processing outputs, the user selected data will be -saved in disk and for resume data outputs, which are supposed to be less frequent, all the data will be saved in disk.
-The wear volume loss calculated by the wear algorithm was added as a triangle property.
Usability Improvements
-New User Interface look and feel was created.
-The dark theme has become the default one.
-An option to invert the normals of surface geometries was created.
-The ability to set transparency for Particles entity in the 3D view was added.
-The wheel mouse controls were standardized with other Ansys products.
-The ability to reload CFD Coupling files was added for both Fluent 1-way and 2-way coupling methods.
-The terminology related to output frequencies was updated.
-The ability to duplicate 3D views was added.
-The ability to save custom properties and curves in the Project scope was added.
Documentation Improvements
-User Manual, DEM Technical Manual, CFD Coupling Technical Manual, SPH Technical Manual, and Verification and Validation Manual, are now in Ansys Help.
All module documentation has been added into a single manual, Module Manual, that is also in Ansys Help.
Bug Fixes
-The problem where Rocky windows installation would create a wrong shortcut to the Ansys License Client Settings was fixed.
-The error caused by the usage of Grace drag model in Fluent during a 2-way coupling was fixed.
-The crash caused by the collision of a single concave particle with a wall before other particles were injected in the domain was fixed.
-The problem in which the orientation set in a geometry was not being considered in the volumetric inlet fill algorithm was fixed.
-The problem that was preventing Rocky to import .cas .h5 files as geometries was fixed.
-The problem that was preventing saving for restart in a 2-Way Coupled simulation with moving mesh was fixed.
-The problem in which a simulation with Radl. et al model would lead to wrong mixing efficiency results was fixed.
-The problem that was leading to wrong statistics caused by the combination of discrete breakage and Joint statistics was fixed.
-The problem in which flexible shells would allow SPH elements to pass through the joints was fixed.
-The error caused by the creation of a Polyhedron Processes through the API:PrePost was fixed.
-The problem in which users were unable to export of Fluent for a 1-way coupling simulation in headless mode (i.e. without a user interface) was fixed.
-A problem where Rocky would crash in simulations with wear model was fixed.
The problem in which particles equal to each other with same relative velocity with respect to the fluid would experience different drags was fixed.
-The problem in which boundary thermal coupling with Fluent would throw and error related to differences in number of nodes was fixed.
-The problem in which the existence of two linked systems in Ansys Motion would lead the Rocky-Motion coupling to fail was fixed.
-The problem in which the multiple selection of particle groups (with mouse click and ctrl) would throw an error message was fixed.
-The problem in which deleting results would corrupted 3D view was fixed.
-The problem in which very large domains combined with SPH Eulerian Solution would lead Rocky to crash without warnings or errors during post-processing was fixed.
-The problem in which Rocky would throw an error when starting a simulation after deleting a geometry linked to a motion frame was fixed
